Mission: Pollock Acoustic-Trawl Survey
Geographic Area of Cruise: Eastern Bering Sea
Date: July 15, 2024
Weather Data from the Bridge:
Latitude: 59° 51.9 N
Longitude: 173° 53.5 W
Wind Speed: 11 knots
Air Temperature: 6.1° Celsius (42.9° Fahrenheit)
Science and Technology Log:
On my cruise, scientists take acoustic measurements along the length of each transect. To ensure that they are accurately estimating the abundance of pollock, they take steps to separate out any backscatter that they believe didn’t come from pollock.
Scientists then apply algorithms to the data in order to estimate pollock abundance over the entire survey area. First, they break up the transect into 0.5 nautical mile (NM) sections and record the average backscatter for that section. Specifically, scientists are interested in the areal density – the amount of backscatter per square nautical mile (NM2).
This data can be challenging to interpret, so one way the scientists represent it visually is with a stick plot over the survey area:
Acoustic backscatter from the 2022 pollock survey.
In this graphic, the transect lines are shown in black, and the density of acoustic backscatter for each 0.5 NM section is represented with a yellow stick. The longer the stick, the greater the density of backscatter at that location.
Scientists then use this data to perform calculations on the entire survey area, including the space in between transects. For each 0.5 NM section of transect, the acoustic density is extrapolated halfway to the next transect on either side.
In this diagram, the red line represents a 0.5 NM section of transect for which acoustic density is calculated. This acoustic density is then applied to the entire pink rectangle, which extends halfway to the next to the transect on either side.
By doing this process for every 0.5 NM section of transect studied, scientists are able to calculate values of acoustic density for the entire survey area.
Map of current survey area and transect lines (black), with boxes (purple) indicating the area over which data from each transect is extrapolated.
Getting from acoustic density to pollock abundance takes another set of calculations, this time making use of trawl data. The pollock caught in each trawl can vary drastically in terms of size – some trawls are mostly juveniles, some trawls are mostly adults, and some are an even mix of both. For a given location, scientists use data from the nearest geographic trawl to estimate the distribution of fish in that area.
In some trawls, the most fish were within 20-30 cm in length (above) while in others, most fish were over 40 cm in length (below).
Having trawl data is necessary to convert the acoustic data into fish abundance because small and large pollock do not reflect backscatter equally. Scientists have studied this, and they have created a relationship for the different backscatter reflected by different length pollock. Using the distribution of pollock in the nearest trawl, scientists are able to proportionally allocate the observed backscatter to pollock of different lengths.
As pollock length increases, backscatter also increases. (Equation from Lauffenburger et al., 2023. Mining previous acoustic surveys to improve walleye pollock (Gadus chalcogrammus) target strength estimates, ICES Journal of Marine Science, Volume 80, Issue 6, August 2023, Pages 1683–1696, https://doi.org/10.1093/icesjms/fsad094)
As an example, let’s simplify the two locations sampled in the graphs above. Suppose the first location had only 20 cm pollock, the second had only 40 cm pollock, and equal backscatter was observed at both sites. Scientists know that, all else being equal, 20 cm pollock produce less backscatter than 40 cm pollock. This means that in order to reflect the same backscatter, there must be a greater number of 20 cm pollock than 40 cm pollock.
By repeating a similar process for each geographic location, scientists are able to estimate the number of pollock in the entire survey area!
Personal Log
The sailing and many of the operations of NOAA Ship Oscar Dyson are done by NOAA Corps officers. I hadn’t heard of the NOAA Corps before sailing, but I’ve since learned that they play an important role in facilitating NOAA research.
To learn more about the experience of NOAA Corps officers, I interviewed Ensign Savi Morales.

Why did you decide to become a NOAA Corps officer?
I’ve always wanted to support the protection of the environment and mitigating climate change. After college, I was trying to figure out where I would contribute the most. I really loved being out on the water, and I had sailed plenty but I wanted to find a way to combine my interests in an environment I contribute the most. The NOAA Corps felt like it was a combination of those things.
I also loved the idea of working with the crew, engineering department, and science. I really enjoy that mixture of groups we have aboard Dyson, which makes every trip’s dynamic different. There’s also a lot of hands-on experience on the bridge deck making our 12 days packed with projects I work on. The NOAA Corps embraces a diverse skill set in order to think and act like a Swiss army knife and be a jack of all trades.
What are your responsibilities on board the ship?
My responsibilities are two 4-hour bridge watches as a Junior Officer of the Deck as I work towards becoming a fully qualified Officer of the Deck. In between my watches I work on tasks related to my responsibilities as the Dyson’s damage control officer, assistant navigation officer, and assistant public affairs officer. I track the sea service hours for our augmenting and personal crew, which they can use to upgrade their license. I maintain flags, and I do monthly safety rounds, inspecting fire extinguishers and fire stations.
What do you enjoy the most about your work?
I enjoy meeting the characters that come to the Dyson, definitely an eclectic but fun group. I also enjoy how much they’ve thrown me into the mix and had me figure things out. It’s a little bit of a trial by fire, but I learn really quick and I’d rather learn by doing.
What part of your job with NOAA did you least expect to be doing?
Checking fire extinguishers, there’s about 100 on board and they all need to be checked monthly. It takes about 3-4 hours.
Here in the Bering Sea you hear about the big, massive waves, but it’s not always like that. The Aleutian Islands are gorgeous with lots of wildlife. I don’t think I’ve seen this many bald eagles, orcas, or puffins in my entire life. They always brighten my day.
What advice do you have for a young person interested in a career in the NOAA Corps?
NOAA Corps requires you to have a four-year college degree in order to apply. Other than that, I’d say find opportunities to go out on the water. There’s high school scholarships, there’s college scholarships. You can also volunteer if you have time. I volunteered at the UC Davis Bodega marine lab. I visited once a week just to hang out with the scientists, with the crew to see if this is what I liked. Be curious and experience things for yourself!
Did you know?
NOAA Corps is one of the country’s eight uniformed services, and its officers operate NOAA ships and aircraft around the country. After completing basic training at the US Coast Guard Academy, NOAA officers assist in fisheries research, seafloor mapping, monitoring atmospheric conditions, and may respond to natural disasters and extreme weather.

Science and Technology Log I’ll start my last blog post with some vocabulary… and a sports analogy. Apologies in advance, I’m testing out some sports jokes to appeal to my 5th-grade sports fans who are skeptical about science. My hope is that the vocabulary (at least) will aid in understanding the following narrative about NOAA Ship Bell M. Shimada’s Leg 3 centerboard retraction.
Don’t worry, it’s not too complicated. It isn’t that different from how rookie Trail Blazer Ibou Badji (Center) was removed for knee surgery at the end of last season… or how the other Center, Jusuf Nurkic, was ejected after an altercation with an opponent and then retracted for the remainder of the same season with plantar fasciitis… Where have all the Centers on the board gone? At least there is more certainty of Shimada’s centerboard returning than Nurkic (even though he has three years on his contract left)!
Vocabulary
Acoustics – In our case, acoustics refers to an entire branch of physics concerned with the properties of sound. Yes, acoustics can also refer to how your voice sounds when singing in the shower.
Sonar – A system for the detection of objects underwater by emitting sound pulses and detecting or measuring their return after being reflected by the objects. The vocabulary words that follow are all related to the sonar system on the Shimada.
Centerboard – A retractable hull appendage, similar to the keel on a sailboat.
Ping – To emit a signal and then listen for its echo in order to detect objects. Sean Connery may have introduced you to the concept. “Give me a ping, Vasili. One ping only, please.” (Captain Ramius, The Hunt for Red October, 1990)
Hertz – One hertz (Hz) is equal to one event per second. The unit’s most common usage is to describe periodic waveforms (as is used in acoustics) and in musical tones. Kilohertz (kHz) is equal to 103, megahertz (mHz) is equal to 106 .
Transducer – A device that converts variations in a physical quantity, such as sound, into an electrical signal, or vice versa. On the Shimada, the transducer emits a ping.
Transceiver – A device that both transmits and receives communication. There are five transceivers on the Shimada, one for each frequency—measured in kHZ—that the scientists monitor. Walkie-talkies are one example of transceivers.
Note: I have a habit of calling things by their incorrect names, and had some confusion about how a “transponder” fits into these “trans” terms. A transponder is a blend between “transmitter” and “responder.” Essentially, a device that receives a radio signal and emits a different signal in response. They are used to detect and identify objects. If you have a car key fob that locks and unlocks your doors remotely (or starts your engine), then you are walking around with a transponder. Transponders are also commonly found in airplanes.
Echosounder – A type of sonar. The Shimada uses a wideband transceiver (WBT) scientific echosounder system for the hake survey.
Echogram – The visualization of sound once the transceiver “listens” to the acoustic return pinged off objects.
Cleaning up is often a sign of good things coming to an end. Whether it’s scraping glitter glue off the tables of my library, or fish scales off stainless steel in the Shimada, both signal the end of a productive work period. On Friday night, August 4th, the Wet Lab crew conducted a deep clean of the space after the last trawl. On Saturday, the net was streamed one last time (for Leg 3 anyway) on our way back to Newport, Oregon. Creatures like pyrosomes, flatfish, and young-of-the-year (YOY) hake that had been stuck in the net were flushed out after a period of time waving goodbye in surface waters. YOY is used interchangeably with the term “fingerlings” in the vocabulary of fish development.
In which I get to “swab the deck”… or swab the baskets in this case.
Another event that occurred Saturday was the raising of the centerboard. The centerboard is always raised at sea and cleaned once in port. “Biofouling mitigation” is the fancy term for centerboard cleaning. This is to ensure sea life, such as barnacles, do not adhere themselves to the surface. A build-up of these stowaways could interfere with the sonar. Hmm, I sense potential here for another sports analogy… something about fouls.
The Survey Crew coordinates with the bridge and the engineers to retract the centerboard. Transducers are mounted on the centerboard so they can be lower than the hull. This reduces bubbles and noise. In the Shimada’s case, bubbles are air pockets created by the movement of the ship’s bow. A centerboard extends the distance between sonar equipment and the activity of bubbles gathered near the hull. When seas are rough enough there can actually be a data dropout that appears as a white line on the echogram.
Elysha Agne, at the centerboard control panel.
Fully extended, the centerboard is 3.4 m below the hull of the ship and 9.15 m below the baseline sea surface. There is a manual option for retracting the centerboard, but it is generally only used if there’s a problem. Automatic operations are the norm, and were used when I observed the procedure.
Officers on the bridge slow the ship to 0 knots. The bridge confirms with survey technicians which position the centerboard should be moved to. A control panel for the centerboard is located one deck below the acoustics lab. I stood with Senior Survey Technician, Elysha Agne, to observe the process for retraction. NOAA Corps crew actually push the button on the bridge for retraction, but Agne communicates over the phone with them to confirm what the centerboard control panel is indicating.

Just down the passageway from the control panel are the double watertight doors that provide access to the instrument pod on the retracted centerboard. I include a picture of these doors in the Hook, Line, and Thinker section of blog post, “Let’s Get Specific in the Pacific.”
Once the button is pushed and the centerboard is ostensibly moved, Agne confirms the indicator lights on the control panel and looks through the porthole on the watertight doors nearby to confirm the white letter “R” (for “retracted) is visible on the appendage. Agne turns off the transducers (no pinging) before retraction starts in case the transducers accidentally go out of the water.
This is important because sound travels differently through air than in water. If the transducer were still pinging while a crewmember had their head through the open centerboard access doors—that wouldn’t be good for human ears. The transducer can actually be damaged beyond repair if it pings in the air. The centerboard actually has holes in it, so it fills with water when lowered, then drains as it is raised. I could hear the water draining during the retraction process.

Joshua Slater, CO (Commanding Officer) Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.
I’m responsible for the safety of the ship and its 41 crewmembers (depending on the voyage), including safe navigation, accomplishment of science missions, project management, budget, personnel, and training of the crew.
What’s your educational background?
I have a Bachelor’s in Marine Biology and a Master’s in Marine Sciences both from the University of North Carolina, Wilmington. I grew up in a Navy family, so we moved all around the world. I don’t consider one place home over another. After graduation, I wanted to go to either California or Hawaii. I got a job as a contractor with NOAA doing free-diving and scuba in Hawaii as a Marine Debris Technician. I removed derelict fishing gear and nets off the coral reefs of the northwestern islands. I joined NOAA Corps after that. I attended the U.S. Merchant Marine Academy in King’s Point, New York. In the Corps, there’s a 2:3 rotation ratio in years spent on assignments at sea and on land.
I started out on NOAA Ship McArthur II. We sailed from Seattle out to Hawaii, down to South America, Mexico, and up the West Coast of the U.S. to Canada. My assignment after that was emergency response for incidents at sea such as hurricanes and chemical spills. One of those projects was on the Deepwater Horizon oil spill response down in the Gulf of Mexico. My next ship was in South Carolina on NOAA Ship Nancy Foster, where I worked from Massachusetts to Key West, to Galveston, Texas. After that were land assignments in Washington DC, then Chief of Operations at NOAA’s Marine Operations Center for the Pacific (MOC-P) in Newport, Oregon. I’ve bounced between MOC-P and the Shimada in that land-to-sea ratio since then.
In the NOAA Corps, you start out as an Ensign (pronounced “en-sin”). Within 2-3 years you usually get promoted from ensign to Lieutenant junior grade. During your first sea tour, you need to learn how to drive the ship, keep everyone safe, and understand the basics of ship operations. During your second sea tour, you help coordinate logistics for operations. On the third sea tour you’re running all the administrative functions (hiring, firing, discipline), and on the fourth time out hopefully you are experienced enough to be considered for the ship’s Captain, overseeing the safety of the whole ship, and making sure operations are done efficiently. So, as you work your way through your career you also get promoted. Beyond the rank of Lieutenant junior grade, there’s Lieutenant, Lieutenant Commander, Commander, Captain, and then Admiral.
For civilians, Ship Captain and CO may be viewed as interchangeable. In NOAA Corps you can be a commanding officer and be any number of different ranks. In the civilian world, the ship’s boss is called “Captain” or “Master.” Since NOAA Corps stems from military origins, they use “Commanding Officer.”
What took you by surprise about sailing on the ocean?
What took me by surprise was the amount of operations we could do in less-than-ideal weather. You might have a calm day on shore, but at sea it’s usually windy and you have waves of some sort. We do the best we can given the situation.
Why are conditions rougher further out at sea?
A few things. Currents. Wind. Sometimes headlands protect you from wind when you’re closer to shore. How big the waves get is a combination of how strong the wind blows, how long it blows, and over what distance of water. That’s called the fetch. That gives the time needed for the swell to fully develop based on the wind. Wind at a short distance is a wave. Once you get beyond where the wind is that localized phenomenon, further away it’s the swell. While our wind may be calm here, we may still have a big swell because there’s a storm off Hawaii or Alaska. We’re not feeling the wind but we’re feeling the side effects. Or we could just be in the wind, it’s blowing 50, and not that bad right now, but give it 12 hours to develop, 24 hours, and it’s going to be a lot worse. You do what you can given what you have to work with. The ship is seaworthy and can handle a lot of different conditions.
What’s the biggest weather you’ve been in on the Shimada?
Probably 20-foot waves, although waves are not consistently one height, they’re a range. They may be normally 16-18 feet, but you might get a 22-foot wave come through. The ones I’ve been in consistently were about 20.
At what point is it not safe to conduct operations?
It depends what the wind is, what the swell is, whether they’re from the same direction or opposing directions, or 90 degrees off. Sometimes our whole project is in the trough, which means the waves are hitting us from the sides, so we’re rolling a lot. The way transects are laid out for trawling and sampling gets us rolling a lot. If it’s really bad we’ll angle our way from one location to another. We do have safety standards for operations. Once the wind is above a certain limit, or the waves above a certain range in height, we’ll reassess. Usually, we reassess the operation if wind is over 30 knots, but we’ve done ops in 40 knots before. We’ve also done ops in 16-foot waves. There are a lot of variables to be considered, including the type of operation we’re attempting to execute.
We’ll get people who have never been out here before, or we’ll get people that are so focused on the science, they don’t think about safety. My job is to make sure they don’t forget about safety! We have a daily safety meeting of department heads on the ship. There are weekly drills at sea. During monthly safety meetings, we go over accidents in the NOAA fleet. It’s a lot easier to learn from other people’s mistakes. We all want to come home with our fingers and toes!
What advice do you have for a young person interested in ocean-related careers?
Grow where you’re planted. In NOAA Corps, you don’t get to necessarily choose the jobs where you go next. A board of officers chooses for you, based on your skill set and the needs of the service at that time. For example, I can list my preferences, but there’s no guarantee I will get any of them. There have been many times where officers haven’t even received their second or third choice. My advice to everyone is, you may not want to go to a particular assignment or a particular part of the country, but you’re there, so make the most of it. Every place I have been assigned has good qualities, good things to offer. Those are what I choose to focus on. When I talk to some people, they never seem happy no matter where they are. I think that is a mindset issue. One of my favorite quotes is, “Positivity is a superpower.” The term “Shimada-tude” got its start in the early days of the ship’s service to NOAA and is all about positivity. We want to like what we do and want people to like coming out to sea. We want them to have a good experience, and treat everyone with respect.
Do you have a favorite book?
Growing up I often looked for the Newbery Prize Medal seal or the Newbery Honor seal on a book cover when I was walking through the library. I figured if somebody liked it I might as well try it. It’s hard to pick just one book. I tried a lot of the classics and have made my way through most of “The 100 Greatest Books Ever Written.” Some were enjoyed while others were not. I remember taking an interest in The Odyssey and The Iliad, by Homer; Robinson Crusoe, by Daniel Defoe; Shipwrecked, by Robert Louis Stevenson; The Phantom of the Opera, by Gaston Leroux; and Dracula, by Bram Stoker—to name a few.
Lately, I’ve been reading more and more about financial education. One book I recommend is The Richest Man in Babylon, by George Samuel Clason. It uses fictitious ancient parables to give you sound monetary advice, and that is something that I don’t think is really taught anymore.
As for children’s literature, I’ve recently read a few of the Harry Potter books with my son. I remember reading and enjoying The Chronicles of Narnia series, by C.S. Lewis, Island of the Blue Dolphins, by Scott O’Dell; and Where the Red Fern Grows, by Wilson Rawls.
Floating (Food) Facts (& Opinions)
Here’s the part where we “Let them eat hake.” If you can get your hands on some hake through a company like Pacific Seafood (headquartered in Clackamas, Oregon), then you can decide for yourself whether all this fuss over hake is worth the hype.
Hake (Pacific Whiting) is the most abundant commercial stock on the Pacific Coast.
If you aren’t into hake but consume other seafood, use Fish Watch. NOAA Fisheries hosts sustainable seafood profiles with current information on marine fish harvested in the U. S.
The first couple of paragraphs on the Fish Watch site define “sustainable seafood:”
“Sustainable seafood is wild-caught or farmed seafood that is harvested or produced in ways that protect the long-term health of species populations and ecosystems. The United States is a global leader in sustainable seafood. U.S. fishermen and seafood farmers operate under some of the most robust and transparent environmental standards in the world. If the seafood you purchase is caught or farmed in the United States, you can feel confident you’re making a sustainable seafood choice.
Marine wild-capture fisheries in the United States are scientifically monitored and regionally managed. They are enforced under 10 national standards of sustainability through the Magnuson-Stevens Act—exceeding the international standards for eco-labeling of seafood.”
You may have stood in front of the seafood counter and noticed those green (best choice) and yellow (good alternative) labels. I have yet to see red, which means avoid, which seems counter to the marketing impulse of grocery stores. These labels are based on the Monterey Bay Seafood Watch guidelines. Here’s a pocket guide for my West Coast friends. There are a handful of seafood guides you can consult, but not all are created equal. This article from 2017 captures the frustration consumers sometimes have about what fish to choose.
Part of my confusion is often based on the many names a single species has! For example, I just now learned (on the NOAA Fish Watch site) that Bocaccio are rockfish and are the Oregon Red Snapper I recall from shopping trips and meals as a kid. For me, the thing that makes NOAA’s Fish Watch site superior to the rest is the comprehensive overview of each species profiled. You get detailed sections on Population Status, Appearance, Biology, Where They Live, Fishery Management, and Harvest all in one place. Bon appetit!

Fog persisted on our steam north back to Newport. Without the temptation of visibility on the flying deck, I took extra time vacuuming the stateroom… that’s a joke because vacuuming a 4-person stateroom takes all of 5 minutes. In truth, my roommate and I took care to leave our space Pine-Sol fresh for Leg 4. After packing away my gear I bounced around the ship like you might in a hotel room—surreptitiously checking drawers for items you may have forgotten. That last nautical mile seemed to take forever. I kept looking out of the portholes in the acoustics lab to see nothing but white. Excitement for home began to build once it was time to gather on the flying deck and peer through the misty water vapor. Yaquina Bay Bridge slowly materialized, an elevated street floating in the sky, weirdly disembodied from the solid ground that usually frames it. As we went under the bridge the fog disappeared. Beyond, an 80° Oregon summer in the Willamette Valley beckoned. The Wet Lab Crew ate dinner together while the crew of the Shimada safely docked and worked with the port crew to reattach the gangplank. After hugs and handshakes all around it was time to part. My drive home was uneventful save a dramatic sky.
A HUGE thank you to the Shimada crew aboard Leg 3! You welcomed me, answered my questions, allowed me to look over your shoulder, tolerated me taking photographs of you, and clarified things I didn’t understand. You all are amazing. I appreciate your labor and am thrilled to have witnessed you all working in sync to do science! My students at Peninsula thank you as well—even if they don’t know it yet. Your time and attention will enhance not just one, but many ocean-related lessons I share with them in the forthcoming year. A special thanks to my blog editors: Chief Scientist Steve de Blois and XO CDR Laura Gibson. Your feedback polished these meanderings and gave me confidence that I correctly represented NOAA and the hake.
You Might Be Wondering…
What Next?
To complete my commitment to NOAA as a Teacher at Sea I agree to blog, write one science-related lesson, one career-related lesson, and either present at a conference or publish an article about my experience. I’m back in my school building this week and will soon be working on lessons. At least part of the science lesson will follow the path of hake otoliths (ear bones) from the ocean to the lab back on land. Many thanks to Liz Ortiz, Fisheries Technician, for helping me connect the dots on how the otolith contributes to our understanding of Pacific whiting (hake) life cycles. I’ve decided to publish an article, although I will likely also present at a conference in years to come. I have reviewed children’s books for the national journal, School Library Connection, since 2011, and will start my query for publication there.
The sky was blue when we left Yaquina Bay on Day 1, not so on Day 14.

Hook, Line, and Thinker
Do you eat or consume products harvested from the ocean? Where do those products come from?
If the country of origin for products consumed isn’t the U.S. does that country have an equivalent of NOAA that gathers data and prioritizes sustainability in its policies? For context, consider this recent article from NPR: Demand for cheap shrimp is driving U.S. shrimpers out of business. I’m doing a homemade pad thai recipe this week and reading this motivated me to pay attention to where my shrimp came from. All the shrimp choices at Fred Meyer (Kroger) were imported so I went elsewhere (paid more) and found some from the Gulf of Mexico, harvested in U. S. waters.
While you’re eating your own pad thai with U. S. shrimp, or Pacific whiting mac ‘n cheese, consider NOAA Fisheries first-ever National Seafood Strategy, just released on August 9th, 2023.

Parting thoughts from your Teacher-Librarian at Sea as inspired by quotes from a few children’s literature classics.
“Look at that sea, girls—all silver and shadow and vision of things not seen. We couldn’t enjoy its loveliness any more if we had millions of dollars and ropes of diamonds.” ― Lucy Maud Montgomery, Anne of Green Gables
In my current reading of this quote, I can’t help but immediately extract the tension between commerce and being. It seems to be a theme I have returned to again and again throughout my blog posts. To be, to exist on our planet, is dependent on a healthy ecosystem, and a healthy ocean. NOAA Fisheries leans on the scientific method to tackle a barrage of pressures: consumer demand, climate change, economic prosperity, pollution.
We would do well to remember that NOAA is made up of ordinary people. The government, by the people and for the people. Many of these you have met in my interviews. I was at a dinner party recently (since I’ve returned to land) and there’s always someone in the crowd who makes half-joking remarks about “the government.” What? You killed fish in the name of science? What? Do the fisherman have the same opportunity to trawl? C’mon. Who do you think “the government” is made up of? Your uncle with a Ph.D. in physics. Your daughter with a passion for birds. “Things not seen,” are confusing, intimidating, sometimes scary. NOAA is utterly transparent. The amount of unfettered data available for citizen scientists to freely examine on the internet is mind-boggling. Keep asking questions, then ask more questions! Then do some research—ask a librarian for help!
“The sea, the sea, the sea. It rolled and rolled and called to me. Come in, it said, come in.” ― Sharon Creech, The Wanderer
It said “Come in” the loudest when smooth and glassy. While there were no swimming opportunities on board the Shimada, I have since returned to swimming at my local health club. While doing laps and staring at the dirt, hair bands, and Band-Aids at the bottom of the pool I thought about the chemicals, hair bands, and Band-Aids at the bottom of the ocean. This is not what the sea meant when she said, “Come in.” NOAA Fisheries is an integral part of the solution to the problems that face us as a species. Homo sapiens is only one of many species that have a right to thrive—both for our benefit and their own.
“The castle of Cair Paravel on its little hill towered up above them; before them were the sands, with rocks and little pools of salt water, and seaweed, and the smell of the sea and long miles of bluish-green waves breaking for ever and ever on the beach. And oh, the cry of the seagulls! Have you ever heard it? Can you remember?” ― C.S. Lewis, The Lion, the Witch and the Wardrobe
While perusing a glossary of nautical terms in the downtime after a marine mammal watch, I discovered “caravel” a small, highly maneuverable sailing ship used by the Portuguese in the 15th and 16th centuries. The Niña and the Pinta, of 1492 notoriety, were caravels. I wondered whether this term had inspired C. S. Lewis’ naming of Cair Paravel. I will not remember the cry of seagulls so much as I will the cat-like meow of the common murre, at least that’s what they sounded like to me at the time. I’m a compulsive Googler, so that’s how I came upon this Minecraft version of Cair Paravel.
It made me think of my students and how NOAA scientists are the stars of real-world exploration and discovery. Scientists are also world-builders of a sort—reports on their findings influence policy-makers, lawmakers. As science moves forward, it continuously corrects itself as new things are discovered. Listening to the latest science can make or break the world.
And oh, the cry of the scientists! Have you ever heard it? Can you remember?

Science and Technology Log
Second Engineer Justin Halle provided a tour yesterday of the engine room and associated machinery kept running smoothly by the Engineering Department. Four Caterpillar brand diesel engines use about 1,800 gallons of fuel per day, although that number fluctuates depending on operations and weather. There are multiple fuel tanks in reserve that hold 5 – 15,000 gallons. A fuel manifold regulates fluid intake and a camera is fixed on fuel levels so the engineers can monitor them. Two valves per tank allow for filling or suction. Water evaporators separate sludge and water to keep fuel clean and bacteria free. We also looked up the exhaust shaft which vents out the top of the ship above the level of the flying bridge.
We viewed the propellor shaft that drives the main propulsion of the ship. A secondary means of propulsion is the bow thruster, but it is primarily used in close quarters situations such as docking and undocking. We did not view the bow thruster on our tour.

There’s a whole water treatment system. The sewage part has a macerator that blends up, er, things just like the Ninja blender in your kitchen. Treated wastewater is vented to the ocean every few days, but cannot be pumped within three miles offshore or within marine sanctuaries. We consume approximately 1,400 gallons of water per day, and the ship can make potable water from seawater through reverse osmosis, evaporators, and water brought aboard from port. Water is treated with bromine, which is often used as an alternative to chlorine in swimming pools.
Workbenches and tools are kept tidy, with some tools and parts kept in a veritable library of large metal cabinets. An impressive control panel allows the engineers to look at the status of various systems at a glance. Performance logic controllers enable engineers to turn things on or off in the engine room from the control panel. Additional screens show a camera feed of potable water levels, the propulsion system, and the fire pump (only accessible down a hatch in the bow thruster space), which are all prone to flooding. Additional specifications for NOAA Ship Bell M. Shimada can be viewed here.

Matt McFarland, Chief Bosun
Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.
We do a lot of fishing operations and I run all the gear. I run the nets and the winches. I put the nets out wherever the scientists are seeing the fish and we’ll go down to that depth. I’m responsible for the efficiency of the operation and safety of the six deck hands I have underneath me.
Note: Matt is also a “plank owner” meaning he was a member of the ship’s crew prior to the vessel being placed in commission. So, he has been with the Shimada before it was owned by NOAA and still belonged to the shipyard. The ship was built in Moss Point, Mississippi and Matt was a part of the crew when it was taken through the Panama Canal to serve in research operations on the West Coast.
What’s your educational background?
I grew up commercial fishing. After high school I went to a technical college for marine technology. So I can work at marinas, on boats and motors and this and that. After school I went back to commercial fishing for a while along with carpentry to supplement. Then about 2008 I decided I wanted to be a professional mariner and get my U.S. Coast Guard license. From there I found out about NOAA, joined in 2009 and have been here ever since. The Coast Guard license is about a three-week course; they teach you basic seamanship. In order to be in my position out on the ocean you need an AB, meaning able bodied seaman. The Ordinary Seaman (OS) is entry-level and I worked my way up over the years. So on the fishing boats we have different levels: general vessel assistant (OS), fisherman (the equivalent of an AB), the next step is skilled fisherman, then lead fisherman, then Chief Bosun is the leader of the Deck Department.
What do you enjoy most about your work?
I enjoy the ocean. I love being out here. Growing up in commercial fishing, you work really hard and there’s no guarantee you’re going to get paid: if you don’t catch fish you don’t get a paycheck. So being here with NOAA means I get to continue to do what I love and if we don’t catch fish I still get paid. It’s a secure job. I have a passion for getting the science right and making sure things are getting done the way they should be done. We’re making regulations for the commercial industry and if our science is faulty, if we aren’t being efficient, then that’s not fair to them. I have family in commercial fishing, so it’s important to me. A lot of these guys are new to sailing and have never fished, so I’m passing on that knowledge. This isn’t as grueling as commercial fishing. It’s important to me to keep the industry going and get the science right.
What advice do you have for a young person interested in ocean-related careers?
Start with small trips. Make sure you like it. It’s not always beautiful out here. Some days there are rough seas, some people get sick, and for some people it’s just not for them. I would encourage youth to pursue it though. It’s a good way to get away from the news–you’re in your own little world out here. It’s a nice alternative lifestyle.
Do you have a favorite book?
I’d say Captains Courageous, by Rudyard Kipling. The 1937 film version was actually done in my hometown of Gloucester, Massachusetts. Gloucester is the oldest commercial fishing seaport in the United States. (The link will take you to some oral histories of Gloucester residents.)

Give us a brief job description of what you do on NOAA Ship Bell M. Shimada.
My job is the administrative side of the ship which includes staffing, budget, and spending a lot of time at my desk.
What’s your educational background?
I went to college in Myrtle Beach, South Carolina. I have a Bachelor’s in Science with a Geology focus.
What do you enjoy most about your work?
I enjoy the camaraderie of the crew. Sometimes we’ll play games. I have a good time and feel like I’m doing a fine job when they are having a good time.
What advice do you have for a young person interested in ocean-related careers?
If you’re not opposed to sailing, check it out; there’s a high demand. It’s not the easiest lifestyle for everyone. You could be very successful at a young age in a maritime career. There’s a clear path forward. I was a merchant mariner before sailing with NOAA. They call it coming up the hawse pipe when you learn on deck how a ship works. I didn’t go to an academy but learned on the job. I accepted a commission with NOAA as a junior officer and started on NOAA Ship Pisces in Mississippi 14 years ago. While on the Pisces I helped with the cleanup of the Deepwater Horizon oil rig disaster. I was proud to be a part of the fleet of vessels that supported the aftermath of that event.
Do you have a favorite book?
The Gunslinger or Misery, by Steven King. I’m a King fan.
Taxonomy of Sights
Apparently there are more marine mammal sightings in Southern California and fewer as you head north. However, there have been whale spouts sighted every day. Our Chief Scientist says the humpback sightings pick up near Vancouver Island and waters north–although Leg 3 doesn’t extend that far..
Day 8. Bycatch highlights: splitnose rockfish, a 43-lb squid, the egg case of a skate, and a single lamprey. In the evening: whale spouts from the flying deck, and an aerial show from a brown booby (a seabird not normally seen this far north; it may have been a sub-species called Brewster’s brown booby) attempting to land on the jack staff and then on the bow–with limited success in a 24 knot wind Day 9. Saw Humpback flukes as they dove. Day 10. Beautiful shades of ocean blue…

How’s the food?
I am told our Chief Steward, Ronnie Pimentel, is one of the best in the NOAA fleet. Ronnie and Rich Lynch (Second Cook) tirelessly serve up breakfast, lunch and dinner every day. Creamy breakfast grits, blueberry pancakes, pulled pork sandwiches, soups, peanut butter cookies, lamb chops, taco Tuesdays, pizza night, yuuuum. Ronnie has been with NOAA for a year, and prior to that served the Navy 21 years as a Steward. Ronnie spends about $15,000 a month on food, which varies depending on the length of the voyage. Food is stored in two freezers (one large, one small) and two chill boxes (one large, one small). He typically uses about 300lbs of frozen vegetables, and has about one case of each type of food, like one of apples, one of bananas, etc. Depending on the size and tastes of the crew he’ll pack 60lbs of bacon, and various cakes for tempting treats.

Floating Facts
NOAA Corps is the eighth uniformed service in the United States, although it is not an armed force—Army, Navy, Air Force, Marines, Coast Guard, Space Force—and falls under the Department of Commerce, not the Department of Defense (DOD). Interestingly, the U.S. Coast Guard is not under the DOD either, but acts as a military branch and federal law enforcement agency within the Department of Homeland Security. The Public Health Service is the other unarmed, but uniformed service.
NOAA Corps has the same benefits and rank system as the military. Currently NOAA Corps has three admirals. Read more about one of the admirals here. Officers are “active duty” meaning they have full-time employment and may be directed to go where they are needed. The term “billet” refers to the current job in which an officer is placed. Members of the Corps do a rotation of two years at sea and three years on land.

Humor is the best medicine, and a great way to reckon with being cooped up on a ship for two weeks with 33 people. While reading through some posted protocols in the acoustics lab I came across this gem in the last row of “Shimada Sonar Frequencies.”

Another bit of humor comes from the bridge, where there used to be eight camera buttons. For the record, there are NO torpedo tubes aboard NOAA Ship Bell M. Shimada.

I am attempting to collect permissible items from the catch, such as hake young-of-the-year, to take back to my classroom and incorporate in lessons for students. In doing so, I’m getting a crash course in properly preparing wet specimens. My first lesson was that freezing is the best route until items can be processed. This site was helpful to me in figuring out what additional tools I needed to do it properly. While I brought several glass vials for collecting, I did not bring formalin, isopropyl alcohol, or needles. So, for the duration of the research cruise my specimens are in the freezer. I live close to my port of return and so have a personal vehicle to transport items home. For future Teachers at Sea: If you are flying, there are limits in checked baggage. There are also strict rules for shipping. Start your research about shipping hazardous fluids here with FedEx, or here in a publication from Oregon State University.
Librarian at Sea
Librarians specialize in acquiring, organizing, and disseminating information for their target populations. The NOAA Central Library provides access to seminars, journals, NOAA publications, and daily weather maps to name a few. Then there’s NOAA’s Photo Library, which has over 80,000 searchable images in its online database. If you type in “hake” there are 114 results. I anticipate incorporating both databases into future lessons for my students.

Hook, Line and Thinker
The title of today’s post comes from Siletz Nee-Di, an endangered language spoken by some of Oregon’s First People. In 1977, The Confederated Tribes of Siletz were second in the nation and first in Oregon to regain federal recognition. What is now Newport, Oregon was originally home to villages and family groups of the confederation—whose descendants still live in the area.
NOAA Fisheries includes tribal, indigenous, and underserved communities in their strategic priorities for 2023. (See strategy 1.5 in the document available here.) Oregon’s Senate Bill 13 (Tribal History/Shared History) directs educators to include curriculum about contemporary indigenous communities. I am interested in knowing more how NOAA Fisheries partners with local stakeholders in Oregon.
If access to your family’s traditional fishing grounds—a primary source of food and revenue—were suddenly cut off, what would you do to regain entry to those waters?
Read about a Washington state tribal leader who fought for fishing rights and will soon have a U.S. Navy ship named after him.

Science and Technology Log: Longline Fishing
Teacher at Sea Stephen Kade created this graphic to help explain longline fishing.
We have started the longline survey and it is well organized and exciting. The first part of the process is called the set. We start the fishing process by baiting circle hooks. These hooks are attached to a 12 foot length of 3 mm line called a gangion (gan-jin). We use mackerel for bait. Each piece of fish is hooked through a circle hook.
Circle hooks ready for baiting
Next we drop over a buoy with a radar reflector on top called a hi flier. Attached to this is a 4 mm line called the main line. Then a weight is attached to the line and dropped. This anchors the beginning of the fishing line to the seafloor. Next, a numbered clip is attached to each gangion. The gangions are attached to the main line in order from 1- 50. A second weight is then attached to the main line and the process is repeated with gangions numbered 51- 100. A third weight is then attached to anchor this end of the line to the seafloor.
Tagging and attaching the gangions
Finally, a second hi flier buoy is attached and released to mark the end of the line. As each of these steps is done a member of the team records it on a computer. This gives a precise time that each baited hook went in the water as well as when and where the anchors and buoys were released.
Ready to drop the hi flyer
The next step is to take water measurements. This is done with a remarkable device called a CTD. CTD stands for conductivity, temperature and depth. Conductivity is related to how much salt is in the water (salinity) and is related to how well it will conduct electricity. It also measures the temperature and depth of the ocean at that spot. We attach a camera to it to see what the seafloor is made of at that spot. We want to know if it is a sandy bottom, sea grass, muddy, etc.
The CTD
Then we wait one hour.
The second part of the process is called the haul. The haul is simply the set done in reverse, except that we often catch fish. The fishermen use a grappling hook to retrieve the main line attached to the hi flier.
Grappling hook ready to thrown
When it is brought on board, the main line is attached to a winch. The winch is used to pull the main line up of the seafloor. As the main line is pulled in the gangions are detached and replaced in a barrel, the numbered clips are detached and kept on a line in number order. That way, everything is ready to be used for the next set. Whatever is on, or not on, the hook is recorded on the computer. If the bait is missing or damaged is noted.
Weighing a barracuda
Any fish caught is noted on the computer and the team jumps into action. For sharks there are several things that happen. They are identified by species. The hook is removed and the shark is weighed. It is then measured for three different lengths, precaudal (before the tail fin), fork (at the fork in the tail, and total (the end of the tail fin). The sex, male or female, and maturity is determined. Tissue samples are taken by cutting off a small piece of a fin. This tissue sample is placed in a small plastic vial and labeled. They are also often given a numbered tag. This information is all recorded and entered into the computer.

Meet the Crew: Lieutenant James Freed
NOAA Corps Lieutenant James Freed is the operations officer for the Oregon II. He has many responsibilities as part of his job. Part of his job is to liaison, or maintain communication, between the science party and the ship’s commanding officer (CO). That means making sure that everything that the science team needs is on the ship. If the science team has needs then we would go through him and not directly to the CO. As Operations Officer he is also in charge of organizing materials when they come aboard the ship. He posts the Plan of the Day which lets everyone on board know what to expect that day. Lieutenant Freed coordinates port logistics for the ship. This means he coordinates the loading and unloading of materials. His duties also include acting as Officer of the Deck (OOD). During this 4 hour shift he is responsible for the ship’s navigation and safety. His emergency response assignments on the Oregon II include being the nozzleman on the fire team, launching life rafts for abandon ship and he goes out on the rescue boat for man overboard. Lieutenant Freed grew up in Santa Rosa, California. He attended Santa Rosa Junior College and then transferred to University of California, Santa Cruz where he studied marine biology. During this time he worked as an intern on a fishing vessel and this is where he first heard about the NOAA Corps. He has now been in the NOAA Corps for 6 years. Before being assigned to the Oregon II he was first assigned to the NOAA Ship Bell M. Shimada in Newport, Oregon. He then moved to Seattle working with the Marine Mammal Laboratory at Alaska Fisheries Science Center. For this assignment his duties were quite varied. They included doing a lot of field work, flying drones, and doing whale biopsies. Lieutenant Freed is clearly enthusiastic about his career in the NOAA Corps. He describes it as an “incredible career” that supports his growth with leadership and management training. The NOAA Corps is growing with new ships and aircraft and will need to recruit new members.. The ships participate in a wide variety of tasks including fisheries research, oceanographic and atmospheric data collection and hydrographic mapping.
Personal Log
Well these last few days have been quite a transition. After 2 1/2 days of transit from Pascagoula, MS to Miami. It was a bit shocking to see how the skyline has changed after 40+ years. It has grown, to say the least. We started fishing just north of Miami. The 10 person science team is split into two shifts. I am on the “day” shift. We work from noon to midnight. These long shifts are filled with alternating periods of activity and waiting. After the set we wait for an hour before the haul. Then, depending on where the next set is, there will be another wait of between two to three hours. The hauls seem to follow the same patterns. As the mile of line is reeled in, there are long periods with not much happening. Then, there might be three fish online within a few hooks. Last night it was two baby tiger sharks and a 1200 mm (3 ft. 11 in.) barracuda within about 5 minutes. When there is a shark too big to haul up by hand on the gangion, the crane is used. We all don hardhats, the crane is moved into place and everyone is busy taking measurements, preparing tags, and taking tissue samples. I was warned to bring a lot of reading material for the down time and I did that. However, with so many things to learn, interesting people to talk to, and beautiful scenery to watch, I have had little time for boredom to creep in.
Ready to release a baby tiger shark.
One of the most common questions that I had before I left concerned getting motion sick. Dare I utter the word… seasick. So far, I have been lucky… hmm, I can’t seem to find any wood around here to knock on. I started the voyage with what I consider to be a rational decision, take the Dramamine. We started with two days of beautiful weather. By the first sign of rough seas I had stopped taking the Dramamine so I went outside and watched the horizon for about an hour. I decided that watching the horizon on a beautiful day at sea had no drawbacks. I never did feel nauseaus. Some people recomended that I buy the accupressure bands which I did. When seas get rough and I am inside I will sometimes wear those. I have not been seasick, yet. I still take precautions like not doing computer work inside when in rough seas but so far I have been fine. In fact, as far as I know none of the volunteers or crew have been sick.
I cannot end this blog without acknowledging the stewards in the gally and the impressive menu available at each meal. I think that there are always three choices for a main dish and a variety of sides. Additonally, a salad bar is always available, snacks, and my favorite, ice cream.
NOAA fisheries research vessels often work with colleges to help provide experiences for the students by allowing them to come on the ship to collect data for their research. On this leg, Makaila Hernandez was aboard to collect environmental DNA (eDNA) under Dr. Alexis Janosik for the University of West Florida. Water samples are taken from different sampling sights in the Gulf of Mexico. Environmental DNA tells scientists what organisms are in the area of water. DNA can be found in the water when organisms shed materials such as the skin, scales, feces, mucous, and gametes. Once the water is collected, a lab will extract the DNA from the water. The extraction is done in such a way that only the purest form of DNA is obtained. It will then be amplified so that it can go through the DNA sequencing process for organism identification. Collecting DNA for the purpose of knowing what organisms are present is done for several different reasons. It helps check the biodiversity and compare the health of the ecosystem to the previous years.

NOAA Ship Pisces
On this mission we have 28 people aboard Pisces. Without the engineers, technicians, deck crew, and the NOAA corps, the scientists wouldn’t be able to do their job. As most of you know, when things go wrong with a vessel out in the ocean, you have to rely on those within. The engineers work hard and I haven’t gotten to talk with them as much as I would have liked, but after all they have been busy down below keeping the ship going. While touring and visiting the bridge, the amount of technology there and knowledge from the officers on maneuvering the vessel is astonishing. I even had a slight go at it, and with the waves and current my travel line was a bit everywhere and not even close to being as straight as theirs. No worries, they were right by my side the whole time.

Drew Barth, Second Assistant Engineer
Drew grew up in Montana and has been working for NOAA for around 18 years. Drew has worked his way up through the years, and the knowledge he knows about how to keep everything on this ship running is incredible. I had no idea there was so much down below us, and the amount of things that have to be checked and continuously working to keep this working vessel going. Drew tried to summarize all the things he did to me from operating all the equipment (including plumbing, HVAC, engine), maintaining all of the equipment, and every 2 hours all gauges have to be completely checked. At midnight a full report of how much fuel is being consumed as well as other things. Drew said some challenges he has had to deal with are bad weather, flooding, and having to fix multiple things at once. Drew states that working hands-on, growing up with a dad as a mechanic, and taking welding vocational classes really helped him, but training today can be done by attending a maritime school.

Personal Log
Today is our last day at sea. Later this evening we will start working our way towards Pascagoula, MS. We are finishing up our last camera drops and preparing to disembark. I can already tell this morning by looking at the water that we are getting closer to Mississippi. The coloration of the water is more of a brown hue than blue due to the Mississippi River meeting the ocean. Several deck crew are making last minute plans as we prepare to port. I have met so many amazing people from all walks of Earth, and listening to their stories and how they ended up on Pisces is remarkable. There are a lot of hard-working and dedicated people who keep this ship running.
I can’t believe I have been on the ship now for two weeks. I have several more questions from my students back home that I can’t wait to answer when I get back. When I return there are only 10 days of school left, so it will be a whirlwind. I have been blessed to have experienced this, and I have learned so much that I hope to inspire my students to dream big and put themselves out there. I told them before I left how nervous I was and that blogging for the first time ever and doing the unknown was way out of my comfort zone. However, hopefully I have taught them that it is important to take chances and pursue things that they want to do even though they may seem scary. My hopes are to also talk about all the different career paths involved in keeping this mission going aboard NOAA Ship Pisces.
